Description

Technical Field

[0001] The utility model relates to the technical field of gas metering equipment detection, and particularly focuses on a special detection equipment for detecting the pressure-resistant deformation performance of a gas meter under pressure.

[0002] The testing equipment is designed to simulate the internal pressure environment that the gas meter is subjected to in actual use, and can accurately measure the elastic deformation of the gas meter shell under different pressures, so as to comprehensively evaluate the pressure resistance and structural integrity of the gas meter. By performing pressure deformation testing on the gas meter, it is possible to effectively find out whether there are safety hazards such as deformation or cracking under high-pressure conditions, and screen out unqualified products, ensuring that users are provided with gas metering instruments with reliable performance and guaranteed quality, and ensuring the safe operation of the gas supply system. Background Art

[0003] A gas meter is an instrument used to measure gas flow and is usually installed in the pipeline system of a home or industrial site. The appearance of a gas meter is generally a metal or plastic shell with a measuring and counting mechanism inside. The shell of the gas meter needs to have good airtightness to prevent gas leakage, and it also needs to have sufficient pressure resistance to ensure that it will not deform or break under high pressure conditions.

[0004] Since gas is flammable and explosive, once a gas meter leaks, it will bring serious safety hazards. Therefore, it is very important to detect the airtightness of the gas meter. In the prior art, a variety of airtightness detection devices are proposed, such as a gastightness detection device for a gas meter disclosed in Chinese patent CN218937674U. The device uses components such as a vacuum compressor and a positioning cavity seat to perform vacuum sealing detection on the upper and lower shells of the gas meter, which can effectively test the airtightness of the gas meter.

[0005] However, there are few special equipment for testing the pressure resistance of gas meters in the prior art. During the actual use of the gas meter, the gas pressure in the pipeline will fluctuate within a certain range. If the outer shell of the gas meter cannot withstand sufficient internal pressure, it may be deformed, cracked, or damaged, resulting in gas leakage or affecting the accuracy of measurement. Therefore, it is necessary to perform pressure resistance tests on gas meters to ensure that they have sufficient pressure resistance.

[0006] In response to the above needs, it is urgent to develop a device specifically used to test the pressure resistance of gas meters to simulate real high-pressure working conditions and accurately measure the deformation of gas meters under internal pressure, so as to comprehensively evaluate their pressure resistance and ensure the safe and reliable operation of gas meters. The development of this device will help improve the quality control level of gas meters and ensure the safe operation of gas systems. Summary of the invention

[0025] Specific technical solutions

[0026] In conjunction with the accompanying drawings, a gas meter pressure resistance deformation detection device provided by the utility model is further described.

[0027] Embodiment 1, as Figure 1-4As shown, a gas meter pressure deformation detection device includes a base 1, a control box 2 arranged above the base 1, and a fixing seat 11 and a deformation sensor 3 are arranged on the upper surface of the base 1. Among them, the deformation sensor 3 in this embodiment is a conventional commercially available sensor, which can be selected according to actual needs, such as a strain sensor, a displacement sensor or other sensors that can accurately measure tiny deformations.

[0028] Specifically, the fixing seat 11 is arranged at the center of the base 1 for fixing the gas meter to be tested. The deformation sensor 3 is arranged in front of the fixing seat 11 and maintains an appropriate distance from the fixing seat 11 so that when pressure is applied to the gas meter fixed on the fixing seat 11, its deformation can be accurately measured.

[0029] During the test, the gas meter to be tested is fixed on the fixing seat 11, and the pressure control system in the control box 2 injects pressure medium (such as air or liquid) into the gas meter to make the gas meter bear a certain internal pressure. The deformation sensor 3 monitors the deformation of the gas meter under the internal pressure in real time, and transmits the measurement data to the data acquisition and processing system of the control box 2. The control system determines whether the pressure resistance performance of the gas meter is qualified according to the size of the deformation.

[0030] It is worth mentioning that the structural form of the fixing seat 11 can be adjusted according to different models of gas meters to ensure that the gas meter is firmly fixed. At the same time, the specific model, measurement range, accuracy and other parameters of the deformation sensor 3 also need to be selected according to factors such as the size of the gas meter being measured and the expected deformation amount.

[0031] In some embodiments, a pressure device is provided on the bottom surface of the control box 2, and the pressure device includes a fixing platform 41 for fixing the pipeline interface 51 of the gas meter 5, a telescopic rod 42 running through the fixing platform 41, and a pressure block 43 is provided at the bottom end of the telescopic rod 42.

[0032] The telescopic rod 42 can be a controllable telescopic structure such as a hydraulic cylinder rod or a screw rod, which is electrically connected to the drive system of the control box 2 and can achieve up and down reciprocating motion according to a preset program or manual operation. The shape of the pressure block 43 can be matched and designed according to the shape of the pipeline interface 51 to ensure that the pressure can be effectively transmitted.

[0033] When the detection device is in working state, the gas meter 5 to be tested is first placed on the fixing seat 11 of the base 1, and the pipe interface 51 at the outlet of the gas meter is fixed in the fixing platform 41. Then the driving system of the control box 2 drives the telescopic rod 42 to descend, so that the pressing block 43 presses and seals the pipe interface 51.

[0034] At this time, the pressure system in the control box 2 can add pressure medium to the gas meter to simulate the internal pressure of the gas meter under actual use. At the same time, the deformation sensor 3, the telescopic rod 42, and the pressure block 43 are all electrically connected to the data acquisition system of the control box 2, and can monitor and record the deformation data of the gas meter under different internal pressures in real time.

[0035] The advantage of this design is that the pressure block 43 can effectively seal the pipeline interface 51 to prevent leakage of the pressure medium, and at the same time completely transfer the pressure applied to the inside of the gas meter to its shell, making the deformation measurement more accurate. By adjusting the stroke of the telescopic rod 42, the size difference of different models of gas meters can also be adapted.

[0036] In some embodiments, the pressure-applying device further includes an adjustment frame fixed to the bottom surface of the control box 2 , and the adjustment frame includes a cross bar 44 , a displacement block 45 that moves left and right on the cross bar 44 , and a fixing rod 49 .

[0037] The crossbar 44 is arranged horizontally, and both ends are movably mounted on brackets on both sides of the bottom surface of the control box 2 by means of hooks or buckles. The displacement block 45 can slide left and right along the crossbar 44, and is driven to move by a knob, a lead screw nut or other controllable mechanism, thereby adjusting the horizontal position of the fixed platform 41.

[0038] The fixing rod 49 is a vertically arranged round rod or square rod, the upper end of which is firmly connected to the bottom surface of the control box 2 by flange, bolts or welding, and the lower end is hingedly connected to the crossbar 44. With this structural design, the entire adjustment frame can be rotated or tilted in a small range in the vertical direction.

[0039] When it is necessary to detect gas meters of different models, the fixed platform 41 can be moved to a position aligned with the pipeline interface 51 of the gas meter to be tested by first adjusting the position of the displacement block 45 on the crossbar 44. Then the vertical tilt angle of the entire adjustment frame is finely adjusted to keep the pressing block 43 in good concentric contact with the pipeline interface 51, thereby achieving accurate positioning and pressure transmission of the gas meter.

[0040] In some embodiments, it is further explained that the displacement block 45 adopts a semi-enclosed structure and is sleeved on the periphery of the crossbar 44. This design prevents the displacement block 45 from slipping off the crossbar 44 and can well guide the displacement block 45 to perform linear reciprocating motion along the crossbar 44.

[0041] The inner side of the displacement block 45 may be provided with a low-friction slider or ball bearing to reduce the motion resistance with the crossbar 44. The outer side of the displacement block 45 may be processed into a square, hexagonal or other multi-prism shape to facilitate manual twisting or connection with a drive mechanism such as a lead screw sleeve.

[0042] When testing a gas meter, it is first necessary to adjust the position of the displacement block 45 on the crossbar 44 according to the size of the gas meter 5 to align the center of the fixing platform 41 with the position of the gas meter pipeline interface 51. This can be achieved by directly pushing and pulling the displacement block 45 manually, or by remotely controlling the movement of the displacement block 45 through the drive system of the control box 2.

[0043] Once the position of the displacement block 45 is adjusted to a suitable position, the pipeline interface 51 of the gas meter 5 can be clamped into the fixing platform 41, and the pressure block 43 is used to press and seal, and then the subsequent pressure test is performed. If the next model of gas meter needs to be tested, it is only necessary to readjust the position of the displacement block 45 without replacing other parts, and the operation is very convenient and efficient.

[0044] The design of the displacement block 45 enables the detection device to be more flexibly adapted to different types of objects to be detected, thereby improving the versatility of use and shortening the loading and unloading and position adjustment time of the detection object, which is conducive to improving work efficiency.

[0045] In some embodiments, a connecting block 46 is fixed below the displacement block 45, and the interior of the connecting block 46 is a hollow structure for accommodating and guiding the movement of the telescopic rod 42.

[0046] The lower opening of the connecting block 46 is connected to the upper part of the fixing platform 41, and the two can be connected by threaded connection, clamp connection or welding to ensure a secure fixation. A through hole matching the telescopic rod 42 is provided in the central area of ​​the fixing platform 41, so that the telescopic rod 42 can pass through the connecting block 46 and the fixing platform 41 from top to bottom.

[0047] The lower end of the telescopic rod 42 extends out of the lower opening of the connecting block 46 and the through hole of the fixing platform 41 in sequence, exposing the pressing block 43 at the bottom. The shape and size of the pressing block 43 should match the caliber of the gas meter pipeline interface 51 to achieve sealing top pressure.

[0048] With this design, the telescopic rod 42 can be well guided and limited by the through holes of the connecting block 46 and the fixing platform 41 when reciprocating, so as to avoid displacement and vibration. At the same time, the displacement block 45, the connecting block 46 and the fixing platform 41 form a whole, and the position of the displacement block 45 on the crossbar 44 can be adjusted to change the horizontal position of the entire pressure transmission system to meet the detection requirements of different types of gas meters.

[0049] In some embodiments, a top pressure plate 47 is provided at the bottom of the fixing platform 41 and is bent inward.

[0050] The shape of the top pressure plate 47 needs to be customized according to the curvature of the top surface of the shell of the gas meter 5 to be tested. Usually, the top cover of the gas meter is cylindrical or elliptical, so the top pressure plate 47 can present a concave arc or bowl-shaped structure to fit closely with the top surface of the gas meter.

[0051] When the detection device is in working state, the pipeline interface 51 of the gas meter 5 is first fixed in the fixing platform 41, and then the telescopic rod 42 is lowered, and the pressing block 43 presses and seals the pipeline interface 51. At the same time, the pressing plate 47 is also tightly pressed on the top of the gas meter shell.

[0052] In this way, the gas meter 5 to be tested is clamped by the pressure block 43 and the top pressure plate 47, and is in a "top-to-top" stress state. When the control system injects pressure medium into the gas meter, the gas meter shell will be subjected to uniform pressure from both inside and outside, simulating the actual use environment.

[0053] The setting of the top pressure plate 47 avoids the situation where the gas meter housing is deformed by only one-way pressure, making the entire detection process closer to the actual working condition and the deformation measurement data more reliable. At the same time, the top pressure plate 47 will not affect the position adjustment of the displacement block 45 and the connection block 46, which is conducive to the flexible use of the detection equipment.

[0054] In some embodiments, in addition to the above-mentioned top pressure plate 47, the pressure-applying device also includes a fixing ring 48.

[0055] The fixing ring 48 is an annular part, and its inner diameter matches the pipe interface 51 of the gas meter 5 to be tested. During the testing process, the fixing ring 48 needs to be sleeved on the periphery of the pipe interface 51 to play the role of limiting and increasing constraints.

[0056] Specifically, when the detection device is in working state, the pipeline interface 51 of the gas meter 5 is first fixed to the fixing platform 41, and then the telescopic rod 42 is lowered, and the pressing block 43 presses and seals the bottom of the pipeline interface 51. At the same time, the fixing ring 48 also needs to cover the outer side of the pipeline interface 51 from the top.

[0057] The lower end surface of the fixing ring 48 contacts the top of the top pressure plate 47, forming a "top-to-top" force transmission channel. When the pressure medium is injected into the gas meter, the top pressure plate 47 will press the fixing ring 48 upward, and the fixing ring 48 will transmit this force to the pipeline interface 51 and the gas meter as a whole.

[0058] This design not only makes the gas meter deformed by the internal pressure, but also makes the outer shell bear the uniform external pressure formed by the top pressure plate 47 and the fixing ring 48, simulating a more realistic use condition. The restraining effect of the fixing ring 48 also prevents the pipe interface 51 from being twisted or displaced during the force application process.

[0059] In some embodiments, the deformation sensor 3 is not directly fixed on the base 1, but is installed and fixed through a special mounting base.

[0060] The mounting base includes two main components: a mounting platform 31 and a mounting box 32.

[0061] The mounting platform 31 is a plate-shaped or frame-shaped base, which is firmly connected to the bottom surface of the base 1 by bolt connection, welding or other methods, and serves as the foundation of the entire mounting seat.

[0062] The mounting box 32 is arranged at the front of the mounting platform 31. It is a box-shaped or tubular hollow structure, and the deformation sensor 3 is fixedly installed in its inner space. The mounting box 32 can be made of metal or high-strength plastic to ensure structural stability during the detection process.

[0063] The purpose of placing the deformation sensor 3 in the installation box 32 is, on the one hand, to provide physical protection for the sensor, and on the other hand, to facilitate adjustment of the position and angle of the sensor so that it is aligned with the optimal measurement position of the gas meter being measured.

[0064] A wire hole may also be provided on the outer wall of the mounting box 32 so as to lead out a transmission line or a signal line of the deformation sensor 3 and connect it to the data acquisition system in the control box 2 .

[0065] In some embodiments, in order to enable the deformation sensor 3 to adjust the measuring distance between it and the measured gas meter 5, the mounting box 32 is not directly fixed on the mounting platform 31, but is movably connected to the mounting platform 31 through a connecting rod.

[0066] Specifically, the connecting rod is a slender metal rod or shaft, one end of which is hingedly connected to the mounting platform 31, and the other end is hingedly connected to the rear side wall of the mounting box 32. This hinge connection method gives the mounting box 32 the freedom to slide forward and backward relative to the mounting platform 31.

[0067] When adjusting the distance, the position of the installation box 32 can be pushed forward or pulled backward along the axis direction of the connecting rod, thereby changing the distance between the deformation sensor 3 inside the installation box 32 and the measured gas meter 5. The connecting rod can also be provided with a locking mechanism, such as a locking nut, so as to fix the position of the installation box 32 after adjusting to the optimal position.

[0068] This design of adjustable measuring distance can effectively avoid the situation where the deformation sensor 3 is too close or too far from the gas meter, resulting in inaccurate measurement data. At the same time, it also provides a certain flexibility and adjustment space for adapting to gas meters of different models and specifications.

[0069] In addition to adjusting the measuring distance, with the help of the rotational freedom of the connecting rod, the angle of the deformation sensor 3 in the mounting box 32 can also be adjusted to a certain degree of tilt as needed to ensure that the measuring direction is facing the gas meter, thereby improving the accuracy of the measurement.

[0070] In some embodiments, the control box 2 serves as the "brain" of the entire detection device and needs to interact with the operator through some external interfaces.

[0071] The control box 2 is fixed on the top of the base 1 by some pillars 6, so that it can be erected high, which is convenient for operators to observe and control.

[0072] On the front panel of the control box 2, there are integrated human-machine interaction components such as a display screen and control buttons:

[0073] Display includes:

[0074] a) LCD screen 21 - used to display equipment operation status, test data, operation menu and other information;

[0075] b) Counter display 22 - dedicated to displaying real-time numerical pressure readings.

[0076] The control buttons include at least:

[0077] a) Switch 23 - controls the power on and off of the entire device;

[0078] b) Pressure control button 24 - used to manually adjust the pressure value applied to the gas meter under test, which may be in the form of ++ / -- buttons or a numeric keyboard.

[0079] In addition to the above components, other function buttons, knobs, indicator lights, etc. can be set on the front panel of the control box as needed to achieve manual intervention and parameter setting of the detection process.

[0080] Through these human-computer interaction interfaces, operators can easily control the entire process of gas meter pressure resistance testing, such as turning on the equipment, setting pressure value targets, starting pressure increments, observing reading changes, etc., which greatly improves the convenience and operability of the test. At the same time, the data interface and icons on the display can also intuitively feedback the test status and problems found to the operator.

[0081] In some embodiments, in order to increase the stability of the base 1 and facilitate the movement and fixation of the entire detection device, a support foot 12 is provided at the bottom of the base 1.

[0082] The support legs 12 can be made of metal or high-strength plastic, and are usually in the shape of short steel pipes, square columns, or cones with anti-slip patterns, etc. There are generally 3-4 support legs 12, which are evenly distributed around the periphery or corners of the bottom surface of the base 1.

[0083] The present invention has been illustrated and described with reference to the preferred embodiments. However, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims.

[0084] The specific embodiments described herein are merely examples of the spirit of the present invention.
